Question

If a family of six members consumes $78kg$ of cereals in a month.find the quantity of cereals required for a family of four members?

Answer 1

Amount of cereals consumed by a family of six members in a month $=78kg$

Amount of cereals consumed by one family member $$\begin{gathered} =\frac{78}{6} \\ =13kg \end{gathered}$$

Amount of cereals consumed by four members in a family $$\begin{gathered} =13kg\times 4 \\ =52kg \end{gathered}$$

Hence, amount of cereals consumed by four members in a family will be $52kg$.
